Metis

Metis was discovered by S. Synnott of the Voyager team in 1979. It is the moon closest to Jupiter, with a standoff distance of 127,960 km. Metis is one of the small moons, and is about the size of the city of Los Angeles, at about 40 km (25
miles) wide.

Metis and Adrastea may function as shepherd satellites for the Jovian ring
system. As a small moon, the composition and surface features of Metis are unknown.
